The following questions were sent to me by an associate and supporter of the

museum here, who is preparing a talk on the history of scientific collecting

and collerctoras. I would appreciate any comments you may have, as well.

Please reply directly to me (unless the list is interested). I can answer

some of her questions for some fields, but would like to get answers across

the systematics spectrum. Thanks in advance for your time and consideration!

Cheers, Sally Shelton
